Cov Ntawv Thov

Siv hauv kev kho cov dej khib nyiab muaj cov chromium hauv kev lag luam electroplating kev lag luam, kuj tau siv rau hauv cov dawb paug dawb porcelain porcelain.

Hu rau tswj thiab kev tiv thaiv tus kheej
Kev Tswj Xyuas Kev Tsim: Kaw cov haujlwm thiab kev tso pa hauv zos. Muab cov khoom da dej kom nyab xeeb thiab qhov muag. Kev tiv thaiv ua pa: Thaum koj tuaj yeem raug plua plav, koj yuav tsum hnav tus kheej priming daim npog ntsej muag. Thaum muaj xwm ceev lossis kev khiav dim, nws raug nquahu kom hnav cua ua pa. Kev tiv thaiv qhov muag: hnav cov tsom iav kev nyab xeeb tshuaj.
Lub cev tiv thaiv: hnav cov khaub ncaws tiv thaiv kab mob.
Tes tiv thaiv: Hnav hnab looj tes roj hmab.

Cia thiab cov lus qhia kev thauj mus los
Cia Prefountefutions: Khaws rau hauv lub tsev rau khoom txias thiab muaj cua sov. Kom deb ntawm knling thiab cua sov. Ntim thiab sib khi. Nws yuav tsum muab khaws cia cais tawm ntawm cov acids thiab cov tshuaj uas tau pom thiab yuav tsum tsis txhob sib xyaw. Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj xau.

Cov txheej txheem ntim

Cov txheej txheem ntim: Cov thoob khib nyiab fiberboard, plyboard chomel thiab cardboard chim sab nraum lub hnab yas lossis ob-txheej Yas Thoob sab nraum lub hnab yas (khoom); Yas Thoob (kua); Ob txheej ntawm cov hnab yas lossis ib txheej ntawm cov hnab yas, hnab yas woven thiab looj ntaub; Composite yas woven hnab sab nraum lub hnab yas sab nraum lub hnab (polypropylene peb hauv ib lub hnab, polypropenene ob hauv ib lub hnab thiab polyethylene ob hauv ib lub hnab); Cov ntoo nteg ntoo zoo li qub sab nraud cov iav fwj iav sab nraud, hlau capped iav fwj, yas lossis hlau kav); Lub khob raj mis, lub raj mis yas lossis tinned nyias hlau phaj phaj (tuaj yeem) nrog lub thawv hauv qab phaj tawv ntoo, cov thawv roj fiberboard lossis cov plywood.
Kev Ceev Kev Ceev: Lub caij tsheb thauj khoom, cov khoom lag luam txaus ntshai yuav tsum sib sau ua ke nrog cov khoom phom sij sib dhos ntawm kev tshaj lij ntawm kev tsheb nqaj hlau. Ua ntej kev thauj mus los, tshuaj xyuas seb cov ntim ntim ua tiav thiab tau sib khi. Thaum lub sijhawm thauj mus los, xyuas kom cov thawv tsis xau, vau, poob lossis puas lossis ua kom puas. Nws yog nruj me ntsis txwv tsis pub sib xyaw nrog cov kua qaub, oxidants, zaub mov noj ntxiv. Tsheb thauj mus los tsheb yuav tsum muaj kev siv tshuaj ntxuav kom muaj xwm ceev thaum muaj kev tsheb thauj mus los. Thaum lub sijhawm thauj mus los, nws yuav raug tiv thaiv los ntawm tshav ntuj, nag thiab qhov kub.
